The Tigers announced that they designated catcher Omir Santos for assignment (Twitter link). The team placed Alex Avila on the 15-day disabled list, purchased the contract of catcher Bryan Holaday and recalled right-hander Jose Ortega in related moves.
Santos, 31, has been removed from and added to the Tigers' roster a number of times in recent years. He appeared in three games with Detroit this month after the Tigers promoted him from Triple-A Toledo, where he had a .310/.315/.417 batting line in 89 plate appearances. Santos also appeared in 11 games with last year's Tigers team and has MLB experience in four seasons.
